The bodies of two women were found duct-taped together on rocks off the Hudson River in New York City Wednesday.

When police arrived at the scene near Riverside Park at 2:39 p.m., both women were unconscious and unresponsive with "no obvious signs of trauma," according to a statement from the New York City Police Department obtained by Oxygen.com.

Medical responders later pronounced both women dead at the scene. Their bodies were found facing one another, with duct tape around their waists and feet, according to WABC.

Police provided matching descriptions for both women: they both were described as being between 25 and 30 years of age with a medium skin tone and curly, shoulder-length dark hair.

Each was wearing a black jacket with fur trim and black leggings, the police statement said.

Police have released sketches of both women to try to aid in the identification.

Authorities believe the bodies may have washed ashore with the tide and stayed after the tide receded, WABC reports.

The medical examiner is currently working to determine a cause of death.

At least one source has speculated that the cause of death could be suicide.

"They were bound together. There's no visible sign of trauma. It appears to be a suicide pact," a police source told the New York Daily News.

Police are also investigating the possibility that the two could have been lovers, according to the New York Post.
